vlim boundaries not working properly for plot_glm_group_topo

#### Describe the bug When `None` is used as one of the boundaries for vlim in [plot_glm_group_topo](https://mne.tools/mne-nirs/dev/generated/mne_nirs.visualisation.plot_glm_group_topo.html), it is not actually taking the min/max of the data. #### Steps to...

Partially addresses #163 Make the coordinate system recommended if 3D positions are present. *Pending meeting to discuss whether a new symbol is required to enforce it*

Currently, the only symbol for conditional requirement (`+`) is only working with parent objects. There is a need however for a symbol putting conditions on subfields other than parent objects...

No 2D or 3D consistency required in the sourcePos-detectorPos pair specifications

> Also related to this, I think that nothing prevents from having for example only sourcePos3D and detectorPos2D (i.e. one is 2D and the other 3D) based on current notations,...
